Abstract: The paper has analyzed the problem of public transport priority and presented the new theory. The theory is ensured the bus arriving on time, reduced the affection to the other transportation and made a way that was economized to achieve the level of railway transportation. Based on this theory, the paper has constructed the structure frame of the public transport priority system, divided the basic components and defined the functions of components. This paper has given mathematics model as the application condition and discusses the application of this theory in the field of the intelligent public transport. At last we have used VISSIM to simulate this method and analyzed the results.

Key words: public transport priority, the level of public transport, automatic vehicle monitor control, inteligent public transport

摘要： 通过分析现有的公交优先通行技术中存在的问题，提出了基于自动车辆监控的公交优先系统理念，即:提高公交车运行的准点率，尽量减少公交优先通行措施对其它交通方式的影响，以较低的工程造价达到或接近轨道交通的服务水平。在此基础上，构建了基于自动车辆监控的公交优先系统的结构框架并对其子系统进行了划分，给出了作为其应用条件的数学模型，并探讨了基于自动车辆监控的公交优先技术在智能公交领域的应用。最后用VISSIM软件对系统进行了模拟，并时模拟结果进行了时比和分析。
